How to Fix a Tutorial That Blocks All Input Until One Specific Action

Locking input down to a single button feels like a frozen game. Players try to pause or look around and nothing responds, so they assume it crashed. The fix is to gate only the actions that would break the lesson, not all of them.

How to fix it

1. Switch from deny-all to allow-list

Instead of consuming every input and re-emitting the one you want, let everything through and only ignore the specific actions that would advance past the current step. In Godot, return early in _input only for those named actions.

2. Keep universal controls live

Always allow pause, camera look, and accessibility toggles during a tutorial. Blocking these reads as a hang, and it traps players who need to adjust settings mid-lesson.

3. Give visible feedback for blocked actions

When the player presses something you are intentionally ignoring, flash the hint or shake the prompt rather than silently eating the press. Silence reads as a bug; a nudge reads as guidance.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Godot error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
